Dudra, you roll to hit each time. basically, flip a coin, half the time it'll be heads, half the time it'll be tails. don't forget that you can get lucky or unlucky streaks, and that the enemy rolls the dice as well.
EPIC pokemon reference. and i like the fact you can pretty much get almost any one as an ally if you try hard enough (already have 6 party members not counting mardek)
